HYDROGARBON BURNER.

Application filed May 18, 1923. 7 Serial No. 639,932.

This invention relates to burners for burning vaporized hydrocarbon fuel such as that derived from the vaporization of crude oil, kerosene and other similar hydrocarbons.

In burners of this type, the fuel is vaporized by the passage of the same through a preheater before it reaches the openings or jets of the burner. This preheater, ordinarily during the operation of the burner after it has started, is heated from the burning vapor issuing from the jets of the burner. In order to start the burner into operation, one or more starting cups are ordinarily provided into which a certain quantity of the liquid employed in the burner or-some other more easily ignited .fuel is poured and the fuel contained in these cups is lighted to heat up the preheater sufliciently to vaporize the fuel. The starting of the burner in this manner involves some labor and trouble and the heating up of the preheater is a slow operation since the liquid in the starting cups burns with a flame of comparatively low temperature.

One object of the present invention is to produce a burner mechanism for burning vapor produced from hydrocarbon fuels in which the burner may be started more easily and quickly than in burners heretofore devised. With this object in view, a feature of the invention consistsin the provision of a separate starting burner and devices separate from the main fuel supplying devices for supplying fluid fuel thereto. e

As is well known to those skilled in the art, it is desirable to force the hydrocarbon fuel to theburner under pressure. This enables the fuel tank to be placed in any convenient position with relation to the burner and also insures a constant uniform supply of fuel under all conditions.

Another object of the present invention is to provide burners of the class described with improved means for producing the requisite pressure upon the fuel in the main supply tank to deliver the fuel under pressure to the burner.

lVith the latter object in view, a feature of the invention consists in the provision of means for delivering to the main fuel supply tank a constant supply of gas under pressure. In the preferred form of the invention, the starting burner is constructed and arranged to burn gaseous fuel, and this burner is supplied with gas and gas isalso delivered from the main fuel supply tank to produce the required pressure from the same source. I

The invention also comprises certain other novel andimproved features of construction and combinations of parts hereinafter described and particularly pointed out in the claims, the advantages of Which will be readily understood and appreciated by those skilled in the art.

The invention will be clearly understood from the accompanying drawings illustrating the invention in its preferred form and the following detailed description of the constructions therein shown.

In the drawings, Fig. 1 is a view partly in frontelevation and partly in section of a burner mechanism embodying the invention. and

, Fig. 2 is a detail-view in side elevation; illustrating certain of the parts shown in Fig. 1. 1

In the form of the invention shown in the drawings, the burner for burning vaporized hydrocarbon fuel comprises a hollow ring-shaped member indicated at 2 provided with a series of openings 4 through which jets of gaseous mixtures are discharged and arranged to be supplied with a gaseous mixture through an inlet pipe 6. Before the vapor enters the inlet pipe, a certain quantity of air is mixed therewith to form a mixture which will burn withgreat heat. The vaporized oil enters the inlet pipe 6 through a jet 8 and" air enters the pipethrough one or more openings 10 arranged about the jet '8, the air being drawn through these openings by the venturi effect produced at said jet. Before being delivered to the jet 8, the hydrocarbon liquid fuel is vaporized in a suitable preheater. This preheatercomprises a chambered ring indicated at 12, which is connected with the jet 8 by means of suitable piping 14:. The flow of the vapor from the ring 12 into the inlet pipe 6 is controlled by means of a valve 16. The preheater ring 12 is supplied with hydrocarbon liquid fuel through a series of pipes 18 from a main supply tank 20. The fuel from the supply tank'20 is delivered as a liquid through the pipes 18 to the preheater 12. Here it is vaporized by the high temperature of the preheater and is then deliv ered through the pipes 14 to the jet 8 where it is mixed with the proper quantity of air and then passes through the supply pipe 6 to the burner.

The valve 16 is mounted on the inner end of a rod 21 threaded into a part of the piping 14: and carrying at its outer end a hand wheel 23 for turning the same to adjustthe valve.

The preheater 12 is arranged to be heated to start the main burner by means of a small acetylene burner 22 which is cut oii after the main burner is started, the preheater then being heated from the main burner. The acetylene burner 22 is supplied with gas through a series of pipes 24: from a tank Air is mixed with the acetylene before it reaches the burner to form a highly combustible mixture, this air entering one oi? the pipes leading directly to the burner through series of openings .28 in the pipe. The flow of gas through the pipes 2% is arranged to be controlled by cocks 30 and in starting the burner, the cocks are adjusted to supply acetylene gas to the burner and after the burner is'well started, the cook 30 is shut off, the preheater 12 then being heated by the flame from jets 34 formed in the main burner 2.

With this construction, the burner may be started quickly without any trouble and the heating up of the burner to a temperature such that itwill operate etticiently is accomplished in a very short time.

In the present form of the invention, the acetylene gas developed in the generator :26 is utilized to supply pressure to the fuel contained in the supply tank 20. thereby insuring a constantuniform supply of fuel to the burner under all conditions. To this end a series of pipes 36 are provided to conn ctone of the pipes 2% with the upper end of the supply tank 20. The tank 20 is provided with a filling tube 88 secured to the top of the tank and extending theretrom to apoint close to the bottom of the tank and is clearly shown in Fig. 1. The tank is also provided with a discharge pipe 4.0 connected with one of the pipes 18. Thus when the tank 20 is filled or partially filled with liquid fuel, the pressure of the gas in the upper part of the tank above the fuel assisted by the weight the fuel will force the fuel outwardly through the discharge pipe 40 and through the pipes 18 to the burner. In order that the acetylene in the tank may not be discharged through the filling tube 38, the discharge pipe 40 is arranged to extend within the tankand its upper end is located somewhat above the lower end of the filling tube To prevent the acetylene from passing outwardly through the discharge pipe 40 when the supply of fuel in the tank is low, a float is provided ior then closing the discharge pipe.

The upper end oi the filling tube 38 is closed by a cap id. The pipe 36 is'providcd with a cut-oil cock 46 and the tank 20 is provided with a vent pipe 48 which is adapted to be closed by a cutoff cock 50. The'cnt oli cocks and 50 are preferably connected together so that they may be operated in unison, the cock 5O being-closed when the cool 16 is opened and vice'versa. As shown, the cocks are provided with a common operating handle This handle is arranged so when the is in operation, the cock then being opened and the cook 50 closed, the landle turned down so that it s ontop of the cap ed which then closes the filling tube i yhen it is desired to 'iill the tank 20, before the cap may be unscrewed, the handle must be lifted thereby closing the cook 46 and opening the vent cook 50. Thus the cap 4% cannot be removed while the connection between the fuel tank 20 and "the acetylene tank 26 is opened, andthe vent cook 50 is always closed at this time. ,-Thus any escape of the acetylene gas except that wvhich passes oil through the vent tube 18 main burner which reservoir is provided at its lower endwith a conical portion having an opening 56 controlled by an automatic valve 58. This valve is attached to the-lower end of a valve rod 59, the upper end of which 'rod is secured. to a diaphragm-6O se'curedatitsmargin to the wall of the reservoir. The diaphragm 60 is preferably made of sheet rubber and carriesa weight-62 resting on a block 63 secured to the central part of the diaphragm which tends to depress the diaphragm and open the valve. The diaphragm is held up against the action of the weight 2 by the pressure of the gas developed in the tank 26 and passing therefrom upwardly through the/opening 56 into the reservoir. Vith this construction, as the pressure of the within the tank 26 decreases. the valve 58 opens to supply more carbide tothe-tank. The increase in the feed of the carbide causes an. increase in the de gas-tight engagement with its seat.
